According to the invention, a rectangular base plate ( 13 ) is provided, which is made from a flexible and shape-retaining material over which it is possible to glue embossed treatment profiles ( 29, 37 ) used as perforating and/or grooving and/or punching profiles corresponding to perforating and/or grooving and/or punching shapes which can be predetermined. Furthermore, at least two fastening strips ( 17, 18 ) are provided for detachably attaching the punch foil to opposed marginal areas in the stretched state.

FIELD OF THE INVENTION

The invention relates to a perforating, grooving or punching apparatusfor multi-color or single color sheet-fed rotary presses.

BACKGROUND OF THE INVENTION

Multi-color sheet-fed rotary presses comprise several printing and/orvarnishing units, each of which is equipped with a rubber cylinder andan appertaining holding system for a blanket. The utilization of suchmulti-color, offset printing presses for perforating, grooving orpunching of sheets is known in the prior art.

U.S. Pat. No. 3,554,070 which issued to Harry S. Boyd on Jan. 12, 1971discloses a method of gluing perforation strips on a counter-pressurecylinder of a printing and/or varnishing unit and of using this toperforate a sheet supported by the elastic rubber blanket of the rubbercylinder. In this method the perforation strips must be installed on thepoorly accessible and non-removable counter-pressure cylinder so thatthe tasks are difficult and time consuming. Also the correct position ofthe perforation strips on the built-in counter-pressure cylinder isdifficult to find, so that expensive position corrections of the gluedperforation strips before the start of priming are frequently necessary.This results in considerable set-up and installation times.

It is also a disadvantage with the Boyd method that the perforationstrips are installed on the counter-pressure cylinder for only one printapplication and must then be removed once more. All the expenses forlong setup and installation times and the costs of perforation stripsare incurred again with a later print application with the sameperforations.

In addition, the perforation strips press themselves into the rubberblanket of the rubber cylinder and cause abrasion with a negativecontour so that such a relatively expensive rubber blanket can no longerbe used.

A perforation in combination with a running printing is only possible ina non-printed area, since otherwise arching of the sheet and adhesion tothe rubber blanket near the perforation strip occur so that the printingimage is damaged. For a perforation in a printed sheet area, drying andan expensive additional passage through the machine is thereforenecessary.

Furthermore, every sheet arches disadvantageously near the perforationbecause of impressions into the yielding rubber blanket so that thesheet output and stacking can be impeded considerably.

Printing presses with counter-pressure cylinders twice the size ofrubber cylinders are also known. In these printing presses a doubleperforation form can be installed at still considerably higher cost,which is no longer economically sound.

Grooving forms cannot be produced by the above-described methods withsatisfactory results, especially since printed sheets in particularbecome badly frayed in the area of the groove because of the yieldingsupport in the rubber blanket.

Furthermore, DE-OS 23 41 326 discloses a method of gluing perforationstrips on the rubber blanket of the rubber cylinder to perforate a sheetwith this in the direction of the counter-pressure cylinder, whereby thecounter-pressure cylinder is covered by a special, removable stretchedfoil/sheeting. To mount such a special foil/sheeting, foil holdingdevices are required on the counter-pressure cylinder so that saidcounter pressure cylinder can be converted from the normal printingprocess without a sheet to a perforation process with a sheet. Themethod described here can therefore only be used with presses withsuitably equipped counter-pressure cylinders.

It is also a disadvantage here that the perforation form is removedafter a print application from a relatively expensive rubber blanketthat can normally be re-used and must again be installed for a laterpossible print application with the same perforation form. Since theperforation strips press into the relatively soft rubber blanket in thiscase during the perforation process, a print application and aperforation can be carried out with this arrangement in one machinepassage only if the perforation can take place in a non-imprinted sheetarea.

According to the description, the perforation strips are to be glued onthe rubber blanket outside of the machine, i.e. when the blanket hasbeen removed. Installation with the required dimensional precision ishardly possible in practice, since the position of the rubber blanketwith the perforation form applied outside of the press can no longer becorrected after assembly in the press, and dimensional deviation of theouter contour of the raised perforation strips with a rubber blanketmounted cylindrically into the machine from the position of the outercontour when the rubber blanket lies fiat occurs. Thus, when attachingperforation strips on a rubber blanket outside the press, at least arough dimensional precision must be achieved for the perforations, orthe position of the perforation strips must be corrected at high cost inthe press as in the previously mentioned method, so that nosimplification or improvement can be achieved here in this respect.

This process is described especially in combination with a five-cylinderconstruction of the printing groups, whereby two rubber cylindersinteract with a counter-pressure cylinder and wherein particularperforation lines crossing each other are to be attached to a rubbercylinder. This application is restricted to the special five-cylinder.construction.

Treatment profiles in multiple parts are known from the book printingindustry in the form of a tint-printing process, and these consist of afirst perforation, grooving or punching strip which can be glued on, ofa connection layer connected in a detachable manner to same, and acounter-punch strip or counter-grooving strip connected to the formerand also being detachable. Such a counter-punch strip orcounter-grooving strip is serf-adjusting as it is placed on acounter-pressure plate during the first passage, and for this anadhesive surface with a pull-off protective foil is provided. For thefurther treatment of the sheets, the connection layer is pulled off andremoved. Such perforation, grooving or punching processes are carriedout at relatively slow speed in the book printing industry in separatemachine passages. The known multi-part treatment profiles used for thishave a large cross-section and it has been practically impossible to usethem until now in combination with multi-color sheet-fed rotary,presses, in particular because of the yielding support yielding counterstops or the yielding counter-pressure application.

It is an object of the present invention to provide a perforation,grooving or punching device for multicolor sheet-fed rotary presses thatwill reduce the cost for such sheet treatment. This object is attainedby the invention as set forth in claim 1.

SUMMARY OF THE INVENTION

According to claim 1 the apparatus of the invention comprises arectangular base plate made of a flexible and shape-retaining materialon which can be stretched in place on a rubber cylinder instead of arubber blanket by means of the blanket holding system. In addition arectangular base foil/sheeting is provided which is made of a flexibleand shape-retaining material, over which it is possible to stickembossed treatment profiles as perforation, and/or grooving and/orpunching profiles corresponding to given perforation and/or groovingand/or punching forms. At least two attachment strips are provided onthe base plate at a distance from each other (in the built-in state inthe circumferential direction of an appertaining rubber cylinder),preferably in opposed marginal areas of the base plate, and thefoil/sheeting can be detachably attached to opposed marginal areas bymeans of same in a stretched condition.

A great number of improvements and advantages are achieved with such adevice:

The base plate can be installed very rapidly and easily instead of arubber blanket on a rubber cylinder, since the blanket holding systemprovided on the rubber cylinder on the machine side is designed forrapid and easy replacement. According to claim 2, a base plate isequipped for this purpose advantageously with holding rails on opposedmarginal areas, said holding rails corresponding lo those of the rubberblankets for the rotary press model used. To that extent the utilizationof the device is possible universally with all current press models inprinting and/or varnishing plants. Perforation and/or grooving and/orpunching forms can be installed easily and comfortably outside themachine on the punch foil. Thanks to the separable attachment of thepunch foil on the base plate which is then fixedly installed on therubber cylinder, and can combine with the separable attachment, relativeposition corrections between the base plate and the foil/sheeting andthus position corrections relative to a sheet to be treated, can becarried out easily and rapidly without having to change the formsinstalled on the punch foil. The person schooled in the art has knownmeans at his disposal for rapidly separable attachment of the punch foilon the base plate. With this method only a very short set-up time isrequired, e.g. for the conversion of a printing or varnishing group tocarry out a perforation, grooving or punching operation.

The base plate should be sufficiently flexible so that it can bestretched cylindrically on the rubber cylinder, but should on the otherhand be shape-retaining, especially at its surface, and for this reasona plastic plate is especially well suited according to claim 3. Thepunch foil lies on such a surface-stable base plate, whereby the surfaceof the base plate is not impressed or arched during a treatment processand an imprinting on the raised treatment profile, contrary to whathappens with a rubber blanket. In this way the treatment goes from asupport of the process profile on the relatively hard base plate surfaceto the counter pressure cylinder which is as a rule also provided with ahard surface. Thus the perforation and punching profiles cut through thepresented sheet precisely and without arching of the sheet, so thatclean punch and perforation cutting edges of high quality result. Toachieve this, merely a simple and precise gap adjustment between thefoil/sheeting and the surface of the counter-pressure cylinder isrequired, with a gap width equal to the profile height of the processprofiles. This adjustment can be effected by means of the adjustingdevice already provided on the machine side. Similarly, clean grooveforms can also be adjusted and maintained.

Since treatment takes place between relatively hard supporting surfacesand as a result practically no arching of the sheet takes place, thetreated sheets remain plane and smooth as before and can be stackedcleanly and high by means of an automated sheet output. This makes alsoadditional trouble free treatments possible, such as e.g. an additionalpassage through the press.

In a sheet treatment the foil/sheeting does not come into contact with asheet surface in the vicinity of a process profile when the gap isadjusted correspondingly. As a result, and because of the precise,cutting-like treatment, perforations and punch-outs, for example can becarried out in one work operation with printing when the printing colorhas not yet dried, even when the perforations and punches are located inthe imprinted area. Thus drying times in additional passages of thesheets through the press can be avoided, so that possibly considerablecost savings can be obtained.

It is a considerable advantage of this device that the foils/sheetingwith installed perforation, grooving or punching forms can be archivedfor later identical print applications. The cost of such archiving isrelatively low because economic punch foils/sheeting, e.g. thin,preferably 0.18 mm thick plastic foils can be used according to claim 4.Thus, archiving is possible in particular in a space-saving hangingfile.

For subsequent print applications with the same perforation, grooving orpunching forms, these no longer have to be built up at great cost.Merely a quick conversion and attachment of the punch foils alreadyavailable for this is necessary, so that considerable cost savings canbe achieved with such subsequent orders. A punch foil with thecharacteristics of claim 5, treatment profiles can be attached and gluedon especially rapidly and precisely. For this purpose the punch foil isprovided with a perpendicular grid line arrangement as a registrationgrid. The grid lines extend preferably in the axial direction of anappertaining rubber cylinder at millimeter distances from each other.Grid lines adjoining each other in the circumferential direction of anassigned rubber cylinder also have equal distances between lines, butthese are slightly less than 1 mm. These reduced distances between linestake the fact into account that the outer contour of the raised, gluedprocess profiles extends on a larger cylinder diameter than the outerpunch foil surface when the punch foil is stretched cylindrically. Thesedifferences do not yel appear when the punch foil lies fiat, when theprocess foils are glued on. Furthermore, with the above-describedreduction of spaces between lines, machine-specific and sheet-specificconditions can also be taken into account in addition to the cylinderdiameter differences and projections on a plane grid line arrangementwhich can be calculated.

For an accurate-to-size attachment of process profiles the procedureconsists in measuring out the process form on a printing plate model ora sheet model. The numerical values found by measurement are thentransferred into the grid-line arrangement, whereby only thecorresponding numerical values and not the measured values aretransferred. The corresponding glued process profiles then produce theaccurate-to-size process form in the development on the sheet when thepunch foil is stretched cylindrically.

The characteristics of claim 6 can be used for rapid and simpleattachment of the punch foil on the base plate, whereby the possibilityis given to correct the position of the punch foil relative m the baseplate. It is proposed for this purpose to attach the fastening strips soas to be capable of displacement relative to the base plate and capableof being fixed, and to connect the punch foil fixedly and separably tothe fastening strip. For this connection, alignment pins and assignedpunch-outs of the punch foil are used. For a plurality of punch foils inone archive, punch-outs with the same layout must be provided.

According to claim 7, holding strips can also be installed in themarginal areas of the punch foil, and these can then be connected to thefastening strips. Here, too, adjustment zones can be provided between afastening strip and a holding strip, and in that case the fasteningstrips could possibly be attached fixedly to the base plate.

A number of arrangements are generally known for such attachmentscapable of being shifted and fixed. According to claim 8, simple andinexpensive screw and slot connections are used. Depending onconditions, fastening strips in two parts, with one strip part fastenedto the base plate and a second strip part movable relative to the firststrip can be used and/or holding strips between which the base plate orpossibly also the punch foil can be held.

With punch or perforation profiles on the punch foil and withnon-chromed counter-pressure cylinders it is advantageous to preciselyposition opposing counter-punch metal sheets there. This also applies togrooving profiles, whereby in this case counter-grooves must bepositioned precisely. For this claim 9 proposes the utilization ofmulti-part process profiles. These consist of a first perforating,grooving or punching strip glued on the punch foil and a connectionlayer strip, preferably a plastic profile strip, separably connected tosame. A counter-punch sheet metal strip or a counter-groove strip withone adhesive face away from the punch foil covered with a pull-offprotection film is in turn separably connected to it. For installation,the entire multi-part process profile is first glued in precise positionon the punch foil and the latter is mounted into the printing presstogether with the base plate. Following this, the protective film isremoved from the adhesive surface by the counter-punch strip or by acounter-groove strip and the press is typed through once with adjustedpressure, so that the counter-punch sheet metal strips or counter-groovestrips automatically adhere to the counter-pressure cylinder and assumetheir precise position. The connection layer strip is then pulled offand removed. In this manner the position of the counter-punchsheet-metal strip or of the counter-groove strip is fixed precisely andcentered relative to the perforation or punching or grooving profile. Bymeans of counter-punch strips of different heights it is also possibleto produce a combined grooving, punching and perforation form. Precisepositioning of the counter-grooves makes it possible to obtain groovingof book-printing quality. According to claim 10 these process profilesare to be designed for universal utilization in the offset process withlittle width, preferably within a range of 2 mm. The range of 0.7 mm hasbeen shown to be a suitable height of the perforation, grooving orpunching strips, but depending on special conditions other heights canalso be suitable. Examples of embodiments of the invention are explainedin further detail through the drawings.

DETAILED DESCRIPTION

Referring now to the drawings, the invention will now be described inmore detail.

In FIG. 1, a conventional printing and varnishing unit 2 of amulti-color sheet-fed rotary press 1 comprising several printing andvarnishing units 2 is shown schematically. This printing group 2 has aplate cylinder 5 by means of which color 8 is applied on a rubberblanket of a rubber cylinder 3 according to a color passage of aprinting format. The printing format is applied via this rubber cylinder3 on a printed sheet stretched over a counter-pressure cylinder 4. Thisprinted sheet is conveyed in the printing and varnishing unit 2 via asheet conveying cylinder 6 into proximity of the counter-pressurecylinder 4 and is grasped by a paper grasper 9 located on thecounter-pressure cylinder counter-pressure cylinder 4. As a result thesheet is entrained into contact connection in the course of furtherrotation of the counter-pressure cylinder 4 and is imprinted. Followingthis imprinting of the sheet the paper grasper 9 releases the sheetagain so that il can be removed via the sheet conveying cylinder 7.

As can be seen in FIG. 2, the printing and varnishing unit 2 of themulti-color sheet-fed rotary press 1 can be equipped for perforating,grooving or punching of a sheet in accordance with the invention byusing a device 12 for perforating, grooving or punching. For thispurpose a rectangular plastic plate 13 is stretched on tho rubbercylinder 3 of the printing and varnishing unit 2 instead of the usualrubber blanket. As can be seen in FIG. 3, this plastic plate 13 isequipped in marginal areas across from each other in the circumferentialdirection of its assigned rubber cylinder 3 with holding rails 15, 16which correspond to those of the rubber blankets of the given rotarypress model. Thus, the plastic plate 13 can be stretched as rapidly andsimply as a rubber blanket on the rubber cylinder 3 by means of theblanket holding system 14 located on the rubber cylinder 3.

As can further be seen in FIG. 3, fastening strips 17, 18 for a punchfoil 19 are located on the facing marginal areas as seen in thecircumferential direction of the rubber cylinder 3. These fasteningstrips 17, 18 can be screwed to a strip 10, 11 riveted to the undersideof the plastic plate 13 as can be seen in particular in FIG. 4.

The punch foil 19 is provided with punched perforations 20 in opposedareas as seen in circumferential direction of the rubber cylinder 3 asshown in FIG. 5. The punch foil 19 can be hooked by these punchedperforations 20 into correspondingly assigned alignment pins on thefastening strips 17, 18 as shown in FIG. 6.

Perforation and/or grooving and/or punching profiles according topredetermined perforation and/or grooving and/or punching forms areglued on the punch foil 19, as is shown for example in FIG. 2 with araised groove profile strip 32 of a process profile 29, whereby acounter-groove strip 30 on the counter pressure cylinder 4 is associatedwith this process profile 29.

For rapid and accurate-to-size attachment and gluing of these processprofiles, the punch foil 19 is provided with a right-angle grid linearrangement 23. Here the grid lines extend in axial direction of theassociated rubber cylinder 3 at distances of one millimeter from eachother. Adjoining each other in the circumferential direction of theassociated rubber cylinder 3, gridlines also have equal distancesbetween lines, whereby these are however, slightly less than 1 mm. Withthese reduced distances between lines the fact was taken intoconsideration that when the punch foil 19 is stretched cylindrically,the outer contour of the raised, glued process profiles comes out to agreater cylinder diameter than the outer punch foil surface.

In order to make a correction of position possible after gluing theprocess profiles on the punch foil 19 and the attachment of the punchfoil 19 on the plastic plate 13, the fastening strips 17,18 are designedwith screw and slot connections 24 so that they can be displacedrelative to plastic plate 13 in the circumferential direction of theassociated rubber cylinder 3. In addition, the punch foil 19 can be withprovided with holding strips in the circumferential direction of theassociated rubber cylinder 3 which are attached by means of screw andslot connections to the fastening strips 17,18 in such manner that anadjustment of the punch foil 19 in axial direction of the associatedrubber cylinder 3 is also possible, but this is not shown here. In thisway a positional correction is possible in the circumferential directionas well as in axial direction of the associated rubber cylinder 3.

For an accurate-to-size attachment of process profiles the desiredprocess forms are first measured on a printing plate model or a sheetmodel. The numerical values thus found are then transferred to the gridline arrangement of the flat 19, whereby no transfer of the metricalmeasured values but only of the corresponding numerical values takesplace. The correspondingly glued process profiles then provide theaccurate-to-size process form in the developed view on the sheet astaken from the model when the punch foil is cylindrically stretched.

On the one hand the plastic plate 13 is flexible so that it can bestretched cylindrically on the rubber cylinder 3. On the other hand itis so stable at its surface that in a treatment process and whenpressure is applied on the raised process profiles, the surface of theplastic plate 13 at that location is not crushed and does not arch, asis the case with a rubber blanket. As a result the treatment of asupport of the process profiles on the relatively hard plastic platesurface is done here on the relatively hard plastic plate surface of thecounter-pressure cylinder 4, which is also provided with a hard surface.Thereby, the perforation and punching profiles cut precisely through thesheet without any arching of the latter so that clean punch-out andperforation edges of high quality result. For this it is merelynecessary to adjust the gap between the punch foil 19 and the surface ofthe counter pressure cylinder 4 very precisely, whereby the gap betweenthe punch foil 19 and the surface equal to the profile heights of theprocess profiles. When stretching and installing the plastic plate 13together with the punch foil 19 and the process profiles, care must betaken that the overall height is precisely equal to maculation ringlevel.

This treatment of the sheets between hard supporting surfaces preventspractically all arching of the sheets, so that the processed sheets canbe stacked plane and flat as before. This also makes additionaltrouble-free treatment possible, e.g. in additional machine passes.

The detachable attachment of the punch foil 19 on the plastic plate 13makes it possible to remove the latter after every print applicationeasily and simply from the base plate 13 and to be archived for possiblelater, identical print applications.

With process profiles placed on the punch foil 19 and non-chromedcounter-pressure cylinders 4 it is advantageous to affix preciselyopposite counter-profiles there. For this purpose the process profile 29is made in several parts in a first embodiment according to FIGS. 8, 9.This process profile 29 comprises a first counter-groove strip 30 whichcan be glued to the counter-pressure cylinder 4 and a connection layerstrip 31 detachably connected to it as a plastic profile strip as shownin FIG. 8.

A groove profile strip 32 is detachably connected to the connectionlayer strip 31 of this first part of the process profile 29 as shown inFIG. 9. This groove profile strip 32 is provided with an adhesivesurface 34 directed upon the punch foil 19 and covered with a pull-offprotective film 33.

To be installed, the process profile 29 is glued via the groove profilestrip 32 in exact position on the punch foil 19 and the latter ismounted in the rotary press 1 with the plastic plate 13 The protectivefilm 33 is then removed from the adhesive surface 34 on thecounter-groove strip 30 and the rotary press 1 is typed through oncewith the pressure adjusted causing the counter-groove strip 30 to adhereautomatically and in precise position to the counter-pressure cylinder4. The connection layer strip 31 is then pulled off and removed. Therebythe position of the counter-groove strip 30 is exactly centered relativeto the groove profile strip 32.

FIGS. 10 and 11 show a second, alternative embodiment of a processprofile 37. This process profile 37 consists of a counter-punch sheetmetal strip 40 as shown in FIG. 10 which is detachably connected to aconnection layer strip 39. As can be seen in FIG. 11, the processprofile 37 furthermore comprises a punch profile strip 38 which isprovided with an adhesive surface 42 covered by a pull-off protectivefilm 41 and which is detachably connected to the connection layer strip39.

Here, too, in order to install the process profile 37 it is first gluedin exact position together with the punch profile strip 38 on the punchfoil 19, and the latter is then mounted with the plastic plate 13 in therotary press 1. The rotary press 1 is then typed through once as for theembodiment of FIGS. 8, 9, so that the counter-punch sheet metal strip 40automatically adheres to the counter-pressure cylinder 4 via theadhesive surface 42′ and assumes an exact position. The connection layerstrip 39 is then pulled off and removed.

Depending on whether the clamping action between the profile strips 32,38 and connection layer strips 31, 39 is weaker or stronger than theclamping force between the counter-strips 30, 40 and the connectionlayer strips 31, 39, the connection layer strip 31, 39 adheres to eitherthe profile strips 32 or 38 or to the counter strips 30 or 40 when therotary press has been typed through.

The process profiles 29, 37 are preferably 2 mm wide while the grooveprofile strip 32 or the punch profile strip 38 is preferablyapproximately 0.7 mm high.
